2 * Unix PuTTY main program.
17 * - Copy-and-paste from the Event Log.
19 * - Remainder of the context menu:
21 * - New Session and Duplicate Session (perhaps in pterm, in fact?!)
22 * + Duplicate Session will be fun, since we must work out
23 * how to pass the config data through.
24 * + In fact this should be easier on Unix, since fork() is
25 * available so we need not even exec (this also saves us
26 * the trouble of scrabbling around trying to find our own
27 * binary). Possible scenario: respond to Duplicate
28 * Session by forking. Parent continues as before; child
29 * unceremoniously frees all extant resources (backend,
30 * terminal, ldisc, frontend etc) and then _longjmps_ (I
31 * kid you not) back to a point in pt_main() which causes
32 * it to go back round to the point of opening a new
33 * terminal window and a new backend.
34 * + A tricky bit here is how to free everything without
35 * also _destroying_ things - calling GTK to free up
36 * existing widgets is liable to send destroy messages to
37 * the X server, which won't go down too well with the
38 * parent process. exec() is a much cleaner solution to
39 * this bit, but requires us to invent some ghastly IPC as
40 * we did in Windows PuTTY.
41 * + Arrgh! Also, this won't work in pterm since we'll
42 * already have dropped privileges by this point, so we
43 * can't get another pty. Sigh. Looks like exec has to be
44 * the way forward then :-/
46 * - Saved Sessions submenu (not in pterm of course)
49 * + we must also implement mid-session reconfig in pterm.c.
50 * + This will require some work. We have to throw the new
51 * config at the log module, the ldisc, the terminal, and
52 * the backend; that's the easy bit. But within pterm.c
53 * itself we must also:
54 * - redo the colour palette if necessary
55 * * might be nice to move this over into terminal.c.
56 * That way we could check which palette entries in
57 * cfg have actually been _changed_ during
58 * reconfiguration, and only update those ones in
59 * the currently visible palette. Also it'd save
60 * some of this hassle in the next port.
61 * - enable/disable/move the scroll bar if necessary
62 * - change the window title if necessary
63 * - reinitialise the fonts
64 * - resize the window if necessary (may be required
65 * either by terminal size change or font size change
67 * - redraw everything, just to be safe.
68 * + In particular, among the above chaos, we must look into
69 * how the choice of font affects the choice of codepage
70 * since the Unix default is to derive the latter from the
73 * - Copy All to Clipboard (for what that's worth)
